Abstract

The purpose of this study was to isolate Pasteurella spp and other aerobic bacterial agents from the lungs of sheep and goats with pneumonia and to identify Pasteurella multocida and Mannheimia haemolytica by both culture methods and polymerase chain reaction (PCR). In addition, mouse pathogenecity tests were carried out on suspected P. multocida isolates. In the examination of lung samples collected from sheep, 15 (4.3%) P. multocida and 8 (2.3%) M. haemolytica strains were isolated and identified. The numbers of species identified in the goat samples were 1 (0.7%) for P. multocida and 6 (4%) for M. haemolytica. The differences between the numbers of P. multocida and M. haemolytica strains isolated from the sheep and goat lung samples were not statistically significant (P = 0.2 in sheep and P = 0.12 in goats). Thirteen (86.7%) P. multocida isolates were positive in the mouse pathogenecity test in sheep. One P. multocida isolate from goats was also positive- in the mouse pathogenecity test. . All P. multocida and M. haemolytica strains that tested positive by culture also tested positive by PCR. However, no toxigenic P. • multocida were detected in any isolates by PCR using primers derived from the toxA gene. In conclusion, this study showed the feasibilty of PCR for the accurate and rapid identification of P. multocida and M. haemolytica.

Özet

Bu çalışmada Pasteurella'ların ve diğer aerobik bakteriyel etkenlerin koyun ve keçilerin pnömonili akciğer örneklerinden izolasyonu ve izole Pasteurella multocida ve Mannheimia haemolytica'mn kültür yöntemi ve polimeraz zincir reaksiyonu (PZR) ile identifikasyonu amaçlandı. Ayrıca şüpheli P. multocida izolatlarına fare patojenite testi yapıldı. Akciğer örneklerinin % 7 koyun kanlı ağarda 24-48 saatlik kültürü sonucunda, 350 koyun akciğerinden 15 (96 4,3) P. multocida ve 8 (96 2,3) M. haemolytica izole ve identifiye edildi. Keçilerden toplanan 150 akciğer örneğinden ise 1 (96 0,7) P. multocida ve 6 (96 4,0) M. haemolytica izole ve identifiye edildi. Akciğerlerden P. multocida ve M. haemolytica'nm izolasyon oranlarının karşılaştırılması sonucunda farkın istatistiksel olarak önemli olmadığı belirlendi (koyunlarda P = 0,2 ve keçilerde P = 0,12). Fare patojenite testi ile koyunlarda 15 P. multocida izolatından 13 (96 86,7)'ü ve keçilerde ise izole edilen bir P. multocida izolatı pozitif bulundu. P. multocida ve M. haemolytica izolatlarının tümünün PZR ile de pozitif olduğu saptandı. Bununla birlikte, toxA geninden hazırlanan primerlerin kullanılması ile yapılan PZR ile P. multocida izolatlarının hiçbirinde pozitif sonuç elde edilemedi. Sonuç olarak bu çalışma, P. multocida ve M. haemolytica'nm doğru ve çabuk identifikasyonu için PZR'nin uygulanabilirliğini ortaya koymuştur.
